Getting started
1 Getting started
1.1 Hardware elements of the Demo Kit
Note: All different versions of the evaluation boards are compatible to each other and can be used in the same
daisy chain.
The following hardware is necessary to start with the TLE9012AQU Demo Kit:
• TLE9012AQU Demo Board
• at least 1x iso UART cable
• 1x resistor ladder (not necessary in evaluation board V5)
• TLE9015QU Transceiver Board
• AURIXTM TC265 TFT Application Kit
• 12 V power supply
•USBcable
• Power supply for resistor ladder (5 V - 60 V)
• optional: 12 Li-Ion cells (instead of resistor ladder)
Figure 2 Demo Kit BMS
1.2 Hardware connection
The hardware is connected as follow:
• The TLE9015QU transceiver board is plugged onto the AURIXTM board (orientation as is Figure 2/Figure 3)

Getting started
• Resistor ladder (cable with orange connector) is connected to the TLE9012AQU demo board (orange
connector) as shown in Figure 3 on the left side. In V5 of the evaluation kit, the resistor ladder is included
on the PCB and connected through a solder bump.
• Supply the resistor ladder with a voltage between 5 V - 60 V
• Supply the AURIXTM board with the 12 V power supply and connector it via the USB cable with the PC
• Use the iso UART cable (blue/white) cable to connect the transceiver board with the sensing board as
shown in Figure 3
Note: The sensing IC board can be connected either to cells or to a power supply with provided resistor ladder
(orange connector with red/black cable). If a resistance divider is used, an open load error is detected and
the corresponding bit in the diagnostsis register (GEN_DIAG) is set (because of that also cell balancing
cannot be activated). This is because the internal resistance of Li-Ion cells is much smaller than that of the
resistors on the resistor divider. All other functions such as cell voltage measurement, temperature etc.
are possible without restriction.
Figure 3 Hardware setup
1.3 13 wire setup
The BMS sensing board can be used in a 13 wire or 15 wire setup (see details in App Note HW). For a 13 wire
setup, solder R13 and R29 with a 0 Ωresistor (0603 package) as descibed in Figure 4.

1.4 Flashing the AURIXTM hardware kit
The following steps are required to setup the frameword for the Demo Kit.
1.4.1 DAS tool
The DAS tool is a USB driver software provided by Infineon. It is required to connect the AURIXTM hardware kit
to the PC environment.
The latest version v7.1.8 can be found here:
Link to DAS tool
To start the installation, administrator privileges are requirement and the terms of use need to be accepted.
After successful installation of DAS, the PC should be able to detect the AURIXTM kit under the com port settings
in the device manager.
1.4.2 Memtool
The Memtool is a software from Infineon for on-chip flash programming.
The latest version v4.8.1 can be found here:
Link to Memtool
Click “Accept & Open” to download the software and run the installation afterwards.
1.4.3 Flash the AURIXTM
The AURIXTM kit needs to be connected to a 12 V power supply. A USB cable connects the board to the PC.

There is the possibility to load a script into the terminal, which will perform several lines of commands. Drag
& drop can be used to load the script in the terminal. A script, which reads out all the cell voltage is provided
on the USB stick “TC265TFT_BMS_init_CVM_1_Slave_Terminal.txt”.

The result registers can be copied into an Excel sheet to calculate the cell voltages (in mV) out of the hex
register values. Therefore, the lines shown in Figure 15 need to be marked and copied by selecting “Edit” ->
“Copy table”.
Based on the “C265TFT_BMS_init_CVM_1_Slave_Terminal.txt” file is an Excel sheet on the USB stick available
to calculate the voltages in mV. The Excel sheet is shown in Figure 16.
